A software developer is using the Cisco Webex REST API and wants to filter messages by date range. Which two query parameters should be included? (Choose two.)
⚠ Common exam trap
Cisco often tests the specific parameter names used in the Webex API (before/after) versus generic terms like start/end or since/until, catching candidates who assume common naming conventions from other platforms.
